I want to be able to keep my HD 4890 in my case and I'm pretty sure mounting a 240 rad inside the case will make it so there is not enough room on the left side of the case for the gpu anymore. Since I only want to cool the cpu just because I want to lose the fan, I'm thinking that I should be fine with a single 120 rad mounted to the right of the case. I'll have a single 5.25" bay res discharge to a pump mounted to the roof to the left of the psu, the pump discharge to the cpu block, the spu discharge to the rad and the rad discharge to the res to compelte the loop.

I haven't decided on which CPU block to get yet because I am still deciding on the tubing. (If anybody could tell me what size is used in the example photo that would be great.)

Does this plan look alright, I want to make sure before I go through with anything. I would just get a corsair H50 cooler but I heard it's a pain to get the AM3 brackets for them.

The best block you can get right now is a swiftech gtz with the am3 mount back. I'm currently using 1/2" ID, 5/8" OD tygon tubing. If you're going to only use a 120 rad you should probably opt for a feser exhanger, its thicker than most radiators, next to that it would be a black ice rad.

Something to add, i see you have 3x2 kits of ram, why did you go that route. doesnt that disable dual channel on your motherboard.

Ok so a 1/2" id would fit comfortably in my v351 you think? I know the measurements I want in mm but I'm not sure what they are in inches, 11/8mm with 8mm as the id. If anyone could convert it for me that would be swell too.

And for the RAM question, I originally had a M4A79T Deluxe but I switched all my parts to the mATX so I could transport it easier
